‘Warp drives‘ may actually be possible someday, study ‘Constant Velocity Physical Warp Drive Solution‘ suggests.

The study provides some theoretical underpinning to warp drives, suggesting that the superfast propulsion tech may not forever elude humanity. Sci-fi fans — especially “Star Trek” devotees — are familiar with warp drives. These hypothetical engines manipulate the fabric of space-time itself, compressing the stuff in front of a spaceship and expanding it behind. This creates a “warp bubble” that allows a craft to travel at incredible velocities — in some imaginings, many times faster than the speed of light. In 1994, Mexican physicist Miguel Alcubierre published a groundbreaking paper that laid out how a real-life warp drive could work. This exciting development came with a major caveat, however: The proposed “Alcubierre drive” required negative energy, an exotic substance that may or may not exist (or, perhaps, the harnessing of dark energy, the mysterious force that seems to be causing the universe’s accelerated expansion).
